Demand for the calendars has taken off faster than they can keep up with, said owner Lorilee Fedler.

"Right now, we're actually on hold because last night we got about 500 requests," she said. "We have a waiting list."

The calendars will be shipped to buyers through Canada Post.

They try to make sure buyers are over 19 and request a piece of ID over email, Fedler told CBC B.C. Almanac host Gloria Macarenko.

She admitted there is no way to verify whether the buyer matches the ID sent online. Despite that and the fact her business is unlicensed, Fedler said she is not concerned about the legality of selling the calendars.

"The reason why I feel OK with them is because Vancouver is a little more relaxed in this area," she said. "People are selling edibles right there on the street, and nobody is doing anything about it."

'Absolutely a concern'

Rebecca Jesseman, a senior policy advisor for the Canadian Centre on Substance Use and Addiction, said there are a number of legal issues with the advent calendars.

"If her organization is not licensed, any distribution is illegal and in terms of a lack of age verification, that is absolutely a concern," Jesseman said.

She said it's an illegal enterprise, but there is a lack of police resources available to enforce cannabis laws right now.

"We are in the midst of an opioid crisis, so are you chasing down somebody that is making a quick profit from advent calendars or are you chasing down someone who is making a quick profit from fentanyl?" she said.

The Vancouver Police Department told CBC it is unlikely to target pot calendars, even though it is outside the current limits of the law.

Jesseman, who has worked with stakeholders in places like Washington and Colorado where recreational marijuana is legal, said being clear on regulations and focusing on education are key.

"[Make] sure that people are aware of the risks and harms that might be associated with use and ways to reduce those risks if they do choose to use," she said. "[Make] sure people are aware of what is legal and what is not legal."
